They start out good then slowly turn on you just like cellphone carriers all do. My download speed is less then 100 KB. They turn you data on an off in the middle of online work..Lots of interruptions 4G 3G drop outs and calls drop out. I have to dial five times or more to make a call.
They only allow known sites like YouTube so they don't get caught. So they throttle ban VPNs or personal IP addresses. I can even stand next cellphone tower an data fails to load webpage takes 10 min to load YouTube or any webpage.
